BILGEPUMP.

SPECIFICATION forming part of Letters Patent No.` 324,438, dated August18, 1885. Application eled'aiuy e, lees. (nmada.)

To all whom, it may concern:

Beit known that I, MICHAEL'WATERS, of Buffalo, in t-he county of Erieand State of New York,haveinvented certain new and useful I1nprovementsin Bilge-Pumps; and I dohere-y by declare that theV followingdescription of my said invention, taken in` connection with theaccompanying sheets of drawings, forms a full, clear, and exactspecification, which will enable others skilled in the art to which itappertains to make and use the same.

My present invention has general reference to improvements in bilge andother pumps; and it consists, essentially, in the novel and peculiarcombination of parts and details of construction, as hereinafter firstfully set forth and described, and then pointed outin the claims.

In the drawings already referred to, which serve to illustrate my saidinvention more fully, Figure 1 is a side elevation of my im' provedpump, partsbeing in section. Fig. 2 is a plan of the same. Fig. 3 isanend`elevation, and Fig. 4 a sectional elevation, in line y y of Fig. l.Fig. 5 is a sectional plan in line x x of said Fig. 1.

Like parts are designated by corresponding letters of reference in allthe figures.

The object of my present invention is the production of a simple,strong, durable, and efficient bilge-pump for vesseluse, wreckingpurposes, &c.; and to attain this end I construct my pump, essentially,of two pumpcylinders, A A', screwed upon a suitable foundation or bedplate, B, by means of screws or bolts b. Each of these cylinders, whichare open on their upper ends, have near their upper ends a flange, a a',to which is secured a connecting-piece, C, forming a dischargeduct forthe pump and at the same time a base for two standards, D, carrying themain crankshaft E, the counter-shaft F, and a worm-wheel shaft, G, whichshafts and suitable gear mechanism, hereinafter mentioned, serve to givemotion to the pumping apparatus.

On the lower ends ofthe cylinders A A are valve-chests H, provided withremovable covers h, securely held in position by means of pivotedscrew-bolts h in the well-known manner, as clearly illustrated in thedrawings.

Upon the base-plate B, inside of the valve- Vchests H, are placed thesuctionvalves I,

lbeing fastened to the base-plate by means of bolts t' andfastening-plates i", as fully illustrated in Figs. l and 5.

In the pump-cylinders are locatedrpistons K, consisting each of hollowmetalliccylinders having in their upper ends heads k, provided with apassage, k', controlled by dischargevalves L, constructed substantiallylike the suction-valves I, and secured to the pistons by means of platesZ and screws Z. In the periphery of the piston are provided metallicpacking-rings m and grooves u, the latter forming a so calledwater-packing, in the usual manner. The pistons K have yokes M, to whichare pivoted connecting-rods N, which in turn are journaled to thewrist-pins O of the cranks P, ahiXed to the outer ends of thecrank-shaft E, and set at right angles to or oppositeeach other, ifdesired.

Upon the crank-shaft E is placed a pinion, Q, which meshes with agear-wheel, R, placed upon the counter-shaft F,together with awormwheel, G', said shaft F having its bearings in boxes s', formed inthe sides of the standards D, and being operated by a worm, G', formedin one piece with or attached to the wormshaft G. This shaft revolves inboXest on the connecting-pieces T, secured to the edges of the standardsD. It is rotated either by means of a crank, U, or by driving-pulleys V,in an obvious manner.

Below the base-plateB of the pump is formed a suction-duct, X,preferably cast in one piece with said base-plate, and provided with twobranches, x zr, so as to take the suction from different points. So hasthe connecting-duct G two branches, c c', to enable the discharge indifferent directions, said discharges being either pipes or spouts, asillustrated in the various figures.

In operation the worm G, engaging the worm-wheel S, causes the rotationof the spurwheel R, which in turn actuates the gear-wheel Q, which,revolving the shaft E, operates the pump in an obvious manner.

It will be readily observed that owing to the peculiar construction ofthe parts and the ease with which each may be disconnected and re- ICOplaced, one of' the pumps may be operated while the parts of the othermay be undergoing repairs, which, in case of an obstruction having gotinto the valve-chambers, &c., is quite an essential point in this pump.To reach the suction valve but four nuts need be turned to swing thepivoted bolts 71 over, when the covers h maybe instantly removed andlthe said valve I disclosed. It will be further ob served that this pumpmechanism,eonsisti ng of the Worm and worm-wheel and spnnwheel andpinion, maybe readily applied to force and other pumps without change ormodification. The worm S is shown as constructed with but asingle threadIt may, however, bemade with any number of threads to suit theconvenience oi' the constructor.

On account of the peculiar construction of the separate pump-cylinderswith connectingv duct, separate uprights and cross-pieces for thebearings of the worm-shaft, any part wearing out o1' breaking from anycause whatever may be readily and easily replaced, so that repairs maybe made at short notice,and therev by much valuable time saved in casesof' emergency.

Having thus l'ully described my invenlion,

I claim as new and desire to secure to me by Leiters laizent of theUnited States- '1. rIhe combination, with the bed-piece andpump-cylinders, of the connecting-duct C, standards D, secured to andupon said connecting-piece C, connecting-brackets T, and the mechanismconsisting of the Worm G', wornrwhecl S, shaft G, spur-wheel It, pinion(Q, shaft E, with cranks l?, and connectingrods N, with pistons K, thewhole being consiructed and combined substantially as and for the objectspecified.

2. In bilge and other pumps, the combination, with the pumpscylinders,of two standards secured to or formed in one piece with the connectingdischarge-duct, a worm-wheel mechanism, and the spurwheel and pinionconnect-ion for giving; motion to the erankshaft, substantially in themanner as and for the object specilied.

In testimony that I claim the foregoing as my invention I have heretosetmy hand in the presence o' two subscribing witnesses.
